- 牙科材料科学 牙科材料科学
- 恢复性牙科 恢复性牙科
- 审美牙科是一种美学牙科.
背景情况:
- 非重要牙漂白涉及各种技术,包括步行漂白剂,室内/室外和办公室方法.
- 有限的比较研究存在于这些不同的非生命漂白协议的有效性.
研究的目的:
- 临床评估和比较三种非重要牙漂白技术的有效性:步行漂白剂,室内/室外和办公室.
- 评估每种方法实现的牙美白的速度和程度.
主要方法:
- 一项随机临床试验涉及54颗变色的非重要牙,分为三个组:步行漂白剂 (酸),室内/室外 (7.5%过氧化) 和办公室 (35%过氧化).
- 使用光谱相量仪 (CIELab坐标) 在基线,每周和治疗后测量颜色变化.
- 统计分析 (ANOVA,费舍尔精确,克鲁斯卡尔-瓦利斯) 与颜色变化 (ΔE00,ΔWID) 和有效性值进行了比较.
主要成果:
- 所有技术都显著改善了牙的亮度 (L*) 和白度 (WID),同时减少了黄色 (a*,b*) 和红色 (b*).
- 过氧化技术 (HP7.5和HP35) 显示,与酸 (SP) 相比,WID的增加明显更大.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
